GENERAL FEATURES The μPS Series 3/3 Phase Uninterruptible Power Supply (UPS) employs Pulse Width Modulation (PWM) and is controlled by a high performance RISC 1 micro-controller. the unit provides a voltage of 3 × 208VAC at a stabilized 60 Hz frequency to any practical load. The system is user friendly. The system can also be connected to the service center via a modem and a telephone line. or to a computer network via an SNMP/WEB agent. The UPS operates on-line and once activated. such as during power surges. Similar status information may be viewed on a computer monitor via an RS232 communications port. to provide reliable. when a power failure occurs. or in case of inverter failure. providing the user with complete up-to-date information.

If the system uses N+1 UPS units (the redundant parallel system). Two topologies are supported: centralized and decentralized. The microcontroller also ensures synchronization of the phase and frequency of the output of all of the UPSs. Up to 10 units can be connected in parallel to feed and backup the same load.2.

In addition. Up to ten units can be connected in parallel.2 Decentralized Parallel Mode of Operation The μPS SP UPS uses a simple “master/slave” hierarchy. where one unit at any given time is designated as the Master UPS and the remaining parallel units are considered Slave UPSs.1 Centralized vs. In decentralized mode each UPS includes its own Static Switch which works independently. because the output voltage is constant even if both UPSs are disconnected. the Static Switch would instantly be triggered and supply the load directly from the mains. 3x208 60 Hz out . Two or more units would then be connected in parallel. The other units are Slaves and follow the Master. and is now responsible for transmitting phase and frequency information to the Slave UPSs. Figure 4 on page 9 shows a cabling diagram for parallel decentralized operation of multiple UPSs. the Static Switches are synchronized using a 3-wire cable. which synchronize themselves accordingly. For additional security.1. 3. This would connect the inverter of the other UPS directly to the mains which could potentially damage the other UPS. Local static switches are inhibited. to avoid such a hazard in decentralized mode. Decentralized Static Switch The UPS employs a Static Switch for functional override. Therefore. PARALLEL OPERATION (OPTION) Each UPS can optionally operate in parallel with similar units as part of a modular UPS system. The function of Master is not dedicated to one of the units. the next UPS in line becomes the Master. One of the system's units takes on the function of Master. to prevent circulation of energy between the UPS units and to isolate the faulty unit from the common power bus. and transmits the phase and frequency information to the Slave UPSs. Special technical solutions are used to synchronize all the units of the system.This method significanly increases system reliability. As illustrated in Figure 5 on page 10. This unit is synchronized to the mains power. When the Master UPS fails. Up to ten units can be connected in parallel. centralized and decentralized.1.
